OR condition in CSS selector

Question

I'm using a CSS selector to look for an element. The same element is present in a script I use across several websites, but it has various classes. Is there a way to determine something similar to that:

css=div[(id='resultVersionA']||[id='resultVersionB')]

Best regards

EDIT

Your solutions work, but not for my next elements

#first-order price, #first price input[type='submit']

To be more clear: In upon query I want to select the button which is under div which is I 'first_order price' OR 'first price'.
